The current default is not ideal in most use cases. Therefore it is

directly. The default is kept as before for console.log and similar.
Using console.dir will now show a depth of up to five and

The current default formatting is not ideal and this improves
the situation by formatting the output more intuitiv.
1) All object keys are now indented by 2 characters instead of
sometimes 2 and sometimes 3 characters.
2) Each object key will now use an individual line instead of
sharing a line potentially with multiple object keys.
3) Long strings will now be split into multiple lines in case
they exceed the "lineBreak" option length (including the
current indentation).
4) Opening braces are now directly behind a object property
instead of using a new line.
5) Switch inspect "base" order. In case the compact option is set
to `false`, inspect will now print
"[Function: foo] {\n property: 'data'\n}"
instead of
"{ [Function: foo]\n property: 'data'\n}".

Change documentation-only deprecation for custom inspection using
`object.inspect` property to a runtime deprecation.
This is a breaking change. Custom inspection via `object.inspect` is
deprecated because there is a more robust Symbol-based alternative to
`.inspect` and the custom inspection via `object.inspect` feature means
that people can accidentally break `console.log()` simply by attaching a
`.inspect` property to their objects. Note that since this is a
deprecation, the custom inspection will still work. The breaking change
is simply the printing of a warning which could alarm users, break tests
or other things that might be dependent on specific output, etc.

If another function has already emitted the deprecation warning with the
same code as the warning that is about to be emitted, do not emit the
warning.
This is a breaking change. Previously, different functions could emit
the same deprecation warning multiple times. This was a known bug rather
than a feature, but this change is being treated as a breaking change
out of caution. Identical deprecation warnings should not be emitted.

Several userland modules have needed this functionality and implemented
it independently. This functionality already exists in Node.js core, so
this exposes it for use by modules. Modules that have needed this
functionality include `lodash`, `concordance` (used by `ava`), and
`qunit`.

are supported. With full-icu enabled, every encoding other than iso-8859-16
is supported.
This provides a basic test, but does not include the full web platform
tests. Note: many of the web platform tests for this would fail by default
because we ship with small-icu by default.
A process warning will be emitted on first use to indicate that the
API is still experimental. No runtime flag is required to use the
